5.6 Dwell Operation
The dwell operation is used to maintain torque during the application and release of
the brakes on lift-type loads. Inverter dwell operation is based on the Acc/Dec dwell
frequency and the dwell time set by the user. The following points also affect dwell
operation:
• Acceleration Dwell Operation: When an operation command runs, acceleration
continues until the acceleration dwell frequency and constant speed is reached
within the acceleration dwell operation time (Acc Dwell Time). After the Acc Dwell
Time has passed, acceleration is carried out based on the acceleration time and
the operation speed that was originally set.
• Deceleration Dwell Operation: When a stop command is run, deceleration
continues until the deceleration dwell frequency and constant speed is reached
within the deceleration dwell operation time (Dec Dwell Freq). After the set time
has passed, deceleration is carried out based on the deceleration time that was
originally set, then the operation stops.
When dr.09 (Control Mode) is set to 0 (V/F), the inverter can be used for operations
with dwell frequency before opening the mechanical brake of lift-type loads, such as
an elevator.
